14 Problematic USB sticks
15 ----------------------
21 Many SanDisk USB sticks are configured by the
22 manufacturer as a fixed disk, and not as a removable disk. As a consequence,
23 they require removing the `live-media=removable` boot parameter, which [[is
24 dangerous|doc/first_steps/bug_reporting/tails_does_not_start#entirely]].
26 * SanDisk Cruzer Edge 8GB
27 * SanDisk Cruzer Extreme USB 3.0 16GB and 32GB
28 * SanDisk Cruzer Fit USB 2.0 8GB, 16GB, and 32G
29 * SanDisk Cruzer Force 8GB
30 * SanDisk Cruzer Glide 4GB, 8GB and 16GB
31 * SanDisk Cruzer Switch USB 2.0 8GB and 32GB
32 * SanDisk Cruzer USB 3.0 64GB
33 * SanDisk Cruzer Blade 4GB, 8GB, and 32GB
34 * SanDisk Cruzer Facet
37 SanDisk had begun the production of flash drives configured as fixed disk in
38 2012 to meet new requirements for Windows 8 Certification, and ended it in mid-2014. The flash drives that
39 comply with this certification will have the Windows 8 logo on their packaging.
40 If a flash drive does not have the Windows 8 logo on its packaging, then that
41 drive will function as a removable disk and should work with Tails.
43 See also [[!tails_ticket 6397]].
49 When installing Tails, PNY USB sticks have problems with the constant write load
50 and are prone to failure.
54 * Staples Relay USB 2.0 16GB, suffers from the same problem as [[some SanDisk USB sticks|known_issues#sandisk]].
56 <a id="isohybrid-options"></a>
61 Booting fails with `Not enough memory to load specified image`. Work around by
62 adding the `mem=1500m` [[boot
63 option|/doc/first_steps/startup_options/#boot_menu]].
65 Acer Travelmate 8573T-254G50M
66 -----------------------------
68 Booting from DVD works fine, but does not start on USB sticks created
69 using Tails Installer.
71 This problem might be corrected in Tails 1.1 and newer: please report
72 your test results back to us.
77 Legacy support needs to be enabled in order to start Tails. To enable
78 legacy boot support, enable 'Launch CSM' under boot (menu).
80 This problem might be corrected in Tails 1.1 and newer: please report
81 your test results back to us.
86 You need to update the firmware to its latest version in order to start from a
87 device installed using Tails Installer.
89 Dell Inc. Latitude E6430/0CPWYR
90 -------------------------------
92 Does not start on USB sticks created using Tails Installer.
94 With BIOS versions A03 06/03/2012 (and A09 and A11)
96 Error message: `Invalid partition table!`
98 Workaround (at least with BIOS versions A09 and A11): just hit enter
99 and it will continue with the boot.
101 This problem might be corrected in Tails 1.1 and newer: please report
102 your test results back to us.
104 Dell XPS L702X/03RG89, Samsung RV520, Samsung Series 7 Chronos
105 --------------------------------------------------------------
107 Does not start on USB sticks created using Tails Installer.
109 We were reported that the legacy BIOS shipped on these systems doesn't
110 know how to deal with the GPT partition scheme installed by Tails
113 This problem might be corrected in Tails 1.1 and newer: please report
114 your test results back to us.
116 <http://en.community.dell.com/support-forums/laptop/f/3518/p/19392884/20010995.aspx>
121 The display panel will have the wrong resolution unless `video=LVDS-1:1600x1200
122 nouveau.noaccel=1` is added to the boot command line. This problem might be
123 corrected in Tails 1.1 and newer: please report your test results back
129 Cannot start neither from USB nor from DVD. System crashes with a blank
130 screen and locked up keyboard. This problem might be corrected in
131 newer versions: please report your test results back to us.
136 With UEFI enabled, when chosing a boot device, select `Boot From EFI File` and
137 then `Filesystem Tails` and `EFI/BOOT/bootx64.efi`.
142 Cannot start Tails 1.1 from USB installed manually in Linux.
147 Goes back continuously to boot menu on Tails installed on DVD.
149 Clevo W258CU, ThinkPad X121e, T420i, T410, T520, W520, T530, E325 and E530
150 --------------------------------------------------------------------------
152 These machines do not start on USB sticks created using Tails USB
153 Installer, due to a firmware limitation.
155 A workaround for some of these machines is to use the [[manual
156 installation process|doc/first_steps/installation/manual/linux]].
157 Note, however, that this technique does not allow you to set up
160 This problem might be corrected in Tails 1.1 and newer: please report
161 your test results back to us.
168 * Some Mac need [rEFInd](http://sourceforge.net/projects/refind/)
169 installed to boot Tails from a USB stick.
170 * MacBookPro5,5 does not boot with Tails in UEFI mode.
171 * MacBook Air 3,2 (A1369 EMC 2392) freezes when booting Tails in
173 * MacBookPro (early 2011) fails to boot from DVD since Tails 1.1.
174 * Mac Pro Tower and MacBook Pro 4,1 (both from early 2008) fail to boot from a USB stick created by

179 Problematic virtual machines
180 ----------------------------
182 Does not start in some virtualization environments, such as
183 QEMU 0.11.1 and VirtualBox 4.2. This can be corrected by upgrading to
184 QEMU 1.0 or VirtualBox 4.3, or newer.
186 See also [[!tails_ticket 7232]] and [[!tails_ticket 7173]].

190 Chainloading Tails from GRUB
191 ----------------------------
193 To workaround problems in booting Tails on laptops with UEFI support, it is
194 possible to chainload the syslinux on the ISO image from another boot loader
195 that is already working on the laptop, like GRUB. Be careful not to modify at
196 all the options of syslinux in the process.
198 The following commands, run from the GRUB shell, might be helpful:
207 Tails might not erase all the system memory on shutdown
208 -------------------------------------------------------
210 On rare systems (non-PAE with big amounts of memory),
211 Tails does not consistently [[!tails_todo
212 more_efficient_memory_wipe desc="erase all system memory as it
215 After using Tails Installer, the "emergency shutdown" doesn't work
216 ------------------------------------------------------------------
218 Tails Installer messes a bit too much with the USB devices for the
219 "emergency shutdown on media removal" feature to continue working after using
220 it. If you believe this feature is critical for the session you're running, we
221 advice you to reboot Tails.
223 Tails DVD eject failure
224 -----------------------
226 Pressing the DVD eject button does not trigger emergency shutdown.
227 Also, the "normal" (non-emergency) shutdown procedure does not eject
230 (Ticket: [[!tails_todo fix_DVD_eject_at_shutdown]])
232 Stream isolation inconsistency in Claws Mail
233 --------------------------------------------
235 Claws Mail isn't using its dedicated Tor SocksPort for Tor hidden
236 service IMAP/POP/SMTP servers (instead Tor's TransPort is used). This
237 is just a deviation from Tails' design and should have no adverse real
240 Tails fails to completely shutdown or restart
241 ---------------------------------------------
243 When stopping Tails on some hardware, the memory wipe procedure fails to
244 complete: the display gets scrambled, but the computer doesn't
245 completely shutdown or restart. Sometimes the caps-lock button light of
246 the keyboard flashes.
248 <div class="caution">
250 When this happens, there is no guarantee that the memory is wiped entirely.
254 This issue has been reported on the following hardware:
256 - Apple when booting from a USB stick:
258 - MacBook Pro 7,1, 13-inch mid 2010
259 - MacBook Pro 9,2, 13-inch mid 2012
260 - MacBook Pro 8,1, 13-inch late 2011
262 - MacBook Pro Retina 11,1, late 2013
263 - Hewlett-Packard HP Pavilion dv6 Notebook PC
264 - Lenovo ThinkPad X61, only on emergency shutdown when pulling out the
266 - Toshiba Satellite C855D
267 - Dell Inc. Studio 1458
268 - Fujitsu Lifebook AH531/GFO, only on regular shutdown, emergency
270 - Apple MacBookPro 10,2

279 <!-- The fingerprints of the Tor browser and the TBB are different: -->
281 * Browser window resizing is in not reliable: [[!tails_ticket 6377]]
282 and [[!tor_bug 10095]].
287 Boot menu has display issues
288 ----------------------------
290 Since Tails 1.1, one some hardware (ThinkPad X230, MacBookPro8,1),
291 the boot menu is not displayed properly. Tails starts fine, though.
293 Connecting to FTP servers is not possible
294 -----------------------------------------
296 Public FTP servers on the Internet are not reachable using Tails.
297 See [[!tails_todo fix_Internet_FTP_support desc="the corresponding
298 task"]] for more details.
300 YouTube videos are hard to get
301 ------------------------------
303 [[!tails_todo easier_YouTube desc="HTML5 video are not easily seen on YouTube"]]. When the
304 message *This video is currently unavailable* appears, the video can actually be viewed.
305 Right-click on the page, select **NoScript** → **Blocked objects** and
306 **Temporarily allow…** the video.
308 Tails will never support videos which require Flash (those with ads).
310 Tails fails to connect to certain Wi-Fi networks
311 ------------------------------------------------
313 This might be related to the introduction of wireless regulation support
316 VirtualBox guest modules are broken for 64-bit guests
317 -----------------------------------------------------
319 VirtualBox guest modules allow for additional features when using Tails as a
320 VirtualBox guest: shared folders, resizable display, shared clipboard, etc.
322 But due to [a bug in VirtualBox](https://www.virtualbox.org/ticket/11037), the
323 resizable display and shared clipboard
324 only work in Tails if the VirtualBox guest is configured to have a 32-bit
325 processor. The shared folders work both on 32-bit and 64-bit guests.
327 Touchpad configurations
328 -----------------------
330 ### Acer TravelMate B113 - ETPS/2 Elantech Touchpad
332 synclient FingerPress=256;
333 synclient TapButton3=0;
334 synclient Clickpad=1;
335 synclient VertTwoFingerScroll=1;
336 synclient FingerLow=1;
337 synclient FingerHigh=1;
339 TorBrowser takes too long to shutdown
340 -------------------------------------
342 Since Tails 0.22, the browser sometimes takes too long to shutdown
343 ([[!tails_ticket 6480]]). Waiting a few more seconds is usually enough
344 to let it close itself correctly.
